Protect your email domain from spoofing and phishing with fully managed DMARC services.
ASK AI – WHY OPUS?
Stop email impersonation before it starts with managed DMARC
Email remains the number one method for cyber attacks and your domain is a prime target. One of the most overlooked, yet essential components of email security is Domain-based Message Authentication, Reporting and Conformance which is commonly known as DMARC.
Without DMARC in place, threat actors can impersonate your business domain to send phishing emails, scam your customers and ultimately put your business at risk. However, this can be prevented with a properly configured DMARC policy which enables you to regain control over who can send emails on your behalf and who is prevented from doing so.
Implementing DMARC is a strategic imperative for any business
DMARC helps manage risk, ensures compliance, and supports business continuity and directly contributes to those outcomes.
Prevents domain spoofing and phishing attacks
With DMARC enforcement, fraudulent emails that pretend to come from your domain are automatically blocked or quarantined by receiving mail servers. This dramatically reduces the risk of any one impersonating your business or attempting spear-phishing activity, not just reducing risk for your employees, but for your customers and partners as well.
Protects your business reputation
In a digital world, your domain is your brand. A compromised domain reputation leads to lost trust, damaged customer relationships, and in some cases, public breaches. DMARC enables you to take proactive ownership of your domain identity and ensure that every legitimate email comes from a verified source.
More key benefits of our managed DMARC solution
Improves email deliverability
DMARC enhances your legitimate email deliverability. By proving that your messages are authentic and properly aligned, you’re less likely to be filtered as spam or junk by major providers like Microsoft 365, Gmail, and Yahoo.
Simplifies regulatory compliance
Whether you’re governed by GDPR, ISO 27001, HIPAA, or another framework, email authentication aligns with key compliance objectives around data protection, identity management, and breach prevention. DMARC also positions you for future policy changes from providers and regulators alike.
Streamline DMARC management across your entire email ecosystem with Sendmarc
Setting up DMARC can be complex especially across multiple domains, brands, or third-party senders. That’s where a platform like Sendmarc becomes essential.
Sendmarc simplifies the entire journey from “monitor only” mode to full enforcement. It continuously monitors your sending landscape, and offers detailed reporting on which messages are passing or failing SPF, DKIM, and DMARC checks. Your team will no longer need to interpret raw XML reports but instead, gain meaningful insights that help you act faster and more confidently.

Full visibility is essential for IT directors managing multi-site environments, complex email infrastructures, or those in highly regulated industries. Sendmarc enables you to;
- Track who’s sending email on your behalf across your business and any third-party platforms
- Identify and shut down unauthorised senders impersonating your domain
- Gradually move towards strict policy enforcement without disrupting operations
- Generate reports for internal audits or regulatory reviews
